If Betty and Veronica went to Tanglewood, they’d stop off first at this retro ’50s hangout in downtown Lenox. It’s the kind of joint that the whole family can agree on; we’re talking burgers (both meat and bean), popcorn chicken, tuna melts and onion rings — finished off with small-batch ice cream and gelato from Berkshire favorite SoCo Creamery. Best of all, nothing on the menu is over $10, so you can save your money for those high-priced symphony tickets.
